An object ID that has type \fBMP_TARGET_PORT_GROUP\fR. The target port group
currently in active access state that the administrator would like the LU
assigned to.

An object ID that has type \fBMP_MULTIPATH_LOGICAL_UNIT\fR.

.SH DESCRIPTION
.sp
.LP
The \fBMP_AssignLogicalUnitToTPG()\fR function assigns a multipath logical unit
to a target port group.
.sp
.LP
Calling this function is valid only if the field \fBsupportsLuAssignment\fR in
the data structure \fBTARGET_PORT_GROUP_PROPERTIES\fR is true. This capability
is not defined in SCSI standards. In some cases, devices support this
capability through non-SCSI interfaces (such as SMI-S or SNMP). This method is
only used when devices support this capability through vendor-specific means.
.sp
.LP
At any given time, each LU will typically be associated with two target port
groups, one in active state and one in standby state. The result of this API
will be that the LU associations change to a different pair of target port
groups. The caller should specify the object ID of the desired target port
group in active access state.
.SH RETURN VALUES
.sp
.ne 2
.na
\fB\fBMP_STATUS_INVALID_OBJECT_TYPE\fR\fR
.ad
.sp .6
.RS 4n
The \fItpgOid\fR or \fIluOid\fR parameter does not specify any valid object
type. This is most likely to happen if an uninitialized object ID is passed to
the API.
.RE

.sp
.ne 2
.na
\fB\fBMP_STATUS_INVALID_PARAMETER\fR\fR
.ad
.sp .6
.RS 4n
The \fItpgOid\fR parameter has a type subfield other than
\fBMP_OBJECT_TYPE_TARGET_PORT_GROUP\fR or \fIluOid\fR has a type subfield other
than \fBMP_OBJECT_TYPE_MULTIPATH_LU\fR.
.RE

.sp
.ne 2
.na
\fB\fBMP_STATUS_OBJECT_NOT_FOUND\fR\fR
.ad
.sp .6
.RS 4n
The \fItpgOid\fR or \fIluOid\fR owner ID or object sequence number is invalid.
.RE

.sp
.ne 2
.na
\fB\fBMP_STATUS_UNSUPPORTED\fR\fR
.ad
.sp .6
.RS 4n
The API is not supported.
